To all whom it may concern .j

Be it known thatiLBoron' D. 'PONTON, a citizenof the United States,residing-atHallettsville, infthe county of'Lavaca and State of Texas, have invented certain new and useful Improvements in Pipe Glamps'j'of which the-following is a' specification'. My inventionrelates to vises, and more, particularly'to an improved'gripping means therefor. f f 3 The principal object of the invention may be said to reside in the provision of a'pair of auxiliary gripping jaws, or Vises, which: may be readily engaged with the oppositely moving jaws of the conventional form of vise, -and maybe quickly removed therefrom, in orderthatthe auxiliary jaws of different size may. thus providing for meanswherebya section,

of piping or other material "may be quickly and securely clamped withinxthe vise.-

The invention has-more especial reference to the novel manner in-which the=auxiliary jaws are arranged, the same being engaged with an expansible spring element, whereby, they will at all times,1be heldin con: tact with the jaw facesfof thevise, conse q uently 'preventin the i displacement :of': the former when the fevice is, loosened ordisengagedfromthe material as previouslyheld thereby.

" i-Anothervirnportant characteristic -of the inventlon, residesin the provision of'abut- ,ment fingers, whichv :are. removably received by'the auxiliary :jaws-,-:wh'ereby 'thewsame may be maintainedinipioperposition, with respect to thesaid'visejaws.

The annexed lrawi' "gs and following description sets forth: in detail, certain construction embodying the invention, such disclosed: means, constltuting however, but one i of the various mechanical forms in which the principle of the invention may be used.

In said annexed'drawingsz -a Figure 1 is a side elevation of my im-v proved auxiliary clamping :or gripping aws, I

Fig.2 is a. fragmental end elevation of V one of the jaws,-' showing a portion of the 50 i 2 same" in lan section; ,1 i V Fig. 3 is a transverse section taken on the line 3-3 of Fig. 1,

one of the jaws," illustrating the relative po'- sition of the abutment fingers. f Referring now more specifically to the drawings, wherein like reference numerals indicate corresponding parts throughout the several views,*I provide a pair of gripping or clampingjaws, indicating the same by .the numerals l and 2. To the opposite side faces-of, these jaws, I 'afiix the stri s 3 and 4, by rivets or the 'like,as at 3,jt e lower ends of which extend beyondthe adjacent end portions of the jaws 1 and 2. The said extended endsof the strips 3 and): are providedwith suitable openings, 'thepu'r ose of which will be hereinafterapparent.v he

gripping jaws 1- and2jare providedwith the usual concaved portions upontheir ad'- jac'ent faces which are'serrated as at 5 and 5', whereby a'secti on of piping or other material may be securely held therebetw'een.

Longitudinally extending recesses OTPOOk L ets Gare formed within the opposite sides of the'jaws 1 and 2 and have leaf springs 7 arranged therein, which springs are secured .to the said jawsl by means of set-screws 8. In the lower portionsof the said jaws l and 2, I arrangea set of pockets .9, these pocketsextending transversely of their said .re-

spective jaws and have arranged therein leaf springs 10 similar to thesprings 7, the same being securedin positionby' means' of set- .screwspll I which are embedded within their respective jaws. 'Theselongitudinally and transversely arrangedepockets are adapted I to; receive abutment fingers which comprise strips of spring 'metal'of substantially U-' shape as at 12, one end of which is b enti at right angles thereto, as at 13, this providing for the so-called' abutment finger. By providing these abutment fingers, it will be evident that the-positioning of the auxiliary jaws 1 and .2 with relation to the jaws of the particular device'towhich they are applied willbe greatly facilitated, the said finger serving as means for maintaining the aws 1n proper posltion; Thus,;.when*'the abutment'fingers are inserted within the lon-' git-udinally extending pockets 6, it being notedthat these pockets are of less width than. the'transversely extending pockets 9,

one leg portion of the U-shaped'element is received thereby and isengaged by @the springs 7 which. are arranged withiri. the said pockets, consequently holding the j fingets in position and preventing thea'c'ci dental outward movement thereof. The abutment fingers are inserted Within the transversely arranged pockets 9, the entire U-shaped element 12is receivedthereby and retained therein by means of the leaf spring 10 which engages the one side portion thereof.

"In order to provide for means whereby the auxiliary jaws 1 and 2 will be normally held in engagement with the jaws of the vise to which they are attached, I secure to the extended portions of the strips 3 and 4, the ends-01f a circularexpansible spring 1 1, by .means of bolts 15 which are passed through the openings arranged within the end of saidextension. It will also be noted, that :the bolts 15 will permit the'expau'sible spring 14 to be swung to one side, should the 'samebe in the way when removingor -in- Sorting a pipe within the vise.

Milieu using my improved clamp jaws for asection of pipe or the like in a horizontal position within the vise, the abutment fingers 13 areengaged with their pockets 6 as arranged within the upper endsof the jaws 1 and '2. The aws are then inserted between the vise jaws-and as will be obvious, the expansible springs 14 connected therewith, will cause the same to be spread and engaged with-the said vise jaws, thus preventing accidental displacement thereof. The abutment fingers 13 will engage the adjacent side portions of the vise jaws, .notshown, and consequently will maintain the said auxiliary jaws 1 and 2 in proper position with respect .to the former. WVi'th the attachment thus'in position, the vise may be then tight ened, to clamp the material as arranged between the auxiliary jaws 1 and 2, therein. Should the user desire to clamp apiece of material within a vise and have the same arranged vertically, the abutment fingers 13 are then engaged with the transversely dis posed pockets 9. Thus, when the auxiliary jaws l and 2 are placed between the visc jaws, the said fingers will engage theadjacent side portions of said vise jaws, and consequently, .cause the auxiliary jaWs to be properly received .therebyand maintain the same in proper position at all times. As above stat-ed, should thesprin'gs 1 L interferewith the inserting or removing of a piece ;of material within the vise, the same may be swung at substantially right angles to the strips 3 and at, the bolts 15 serving as the-necessary pivot points.

It is to be understood, that the jaws 1 and 2, if so desired, may be detachably secured to the strips 3 and -i,'thus enablin the user to readily remove the'same' there roin, and to substitute jawsof different size and configuration therefor. However, if so. desired, the jaws may be fixedly secured to their respective strips 3 and 4t, and when it is desired to remove the same in order that jaws of different size may be substituted, the

bolts -w ill-be removed and then replaced when the desired jaws are in position. Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the construction therein disclosed, provided the means stated by any of the following claims Ol dll'le equivalent of said stated .means he emjploye t. v

I therefore claim as my invention 1. An attachment for .vises comprising a pair of auxiliaryjaws, said jaws having pockets formed therein, abutment fingers comprising Ushaped elements having outwardly extending projections formed therellySiLlfl "ll-shaped elements extending, into said pockets, whereby said auxiliary jaws will support said abutment fingers, and said abutment fingers projecting beyond said jaws.-

-2.[An attachment for Vises comprising a pair of auxiliary jaws, said jaws having pockets formed therein, springs carried upon said .pockets, and abutment fingers comprising U-shaped elements having projections extending outwardly therefrom, said U- shaped elements projecting into said pockets, Wherebysaid spring Will hold said elements against displacement, and said. pro jections .beingadapted to support said jaws upona support.

3. An attachment for vises comprising a pair of. auxiliary jaws, :said jaws having pockets formed therein, abutment-fingers comprising. LU-shaped elements having projections extending outwardly therefrom, said *U-shaped elements removably fitting within said pockets, and flat springs secured adjacent .to' theinner end of said pockets and projecting toward the outeryendof said pocket so as tobe in the :path of movement of thevU-shaped elements positioned within said pockets, thus-firmly ibearing upon said U-shaped elements: for holding the; same against accidental displacement and said projections beingfadaptc'd .to support said jaws .upon a support."

4-. An attachment for vises comprising a pair of auxiliary jaws, a flat circularspring pivotally connected to said jaws, and supporting means earried by .said jaws, and said flat springabeinglcapable of being swung to one side .to project-at an angle to said auxiliary jaws.

In-testimony whereofl aiiix my signature in presence of two witnesses.
